Application filed November 14, 1924.

This invention relates to guiding apparatus, and particularly to guiding rods to a coiling machine.

The object of this invention is to provide improved means for guiding material to a predetermined position or apparatus.

One form of the invention is embodied in apparatus for coiling rods, the rods being coiled, removed from the coiling means, and transferred to a conveyor leading to a quenching bath or the like. The rod is guided to the coiling means by a pivotally mounted tube movable out of its operative position to permit the transfer of the coiled rod to the conveyor. The operation of a common pneumatic valve causes the stripping of the coil from the coilingmeans and the tube to be moved to permit the transfer of the coil to the conveyor. However, during the transferring operation compressed air is supplied independently of the stripping control mechanism to pneumatic means associated with the tube, thus re taining the tube in its inoperative position while the stripping mechanism is returned to normal. l/Vhen the coil transferring means returns to its normal position, the independent supply of air is discontinued and the tube returns to its operativeposition. The rod is supplied to the tube from the rolling mill through a pipe, terminating a suiticient dis-' tance from the receiving end of the tube to permit the engagement and withdrawal of the rod. if desired.

Other features of the invention will become apparent as the detailed description progresses, reference beinghad to the acconr panying drawings, wherein v Fig. 1 is a plan view of apparatus embodying the invention; 7

Referring to Figs. 1, 2, and 3, 20 designates generally a coiling machine compris ing a base 21 upon which is mounted a motor 22 adapted to drive a pinion 2t meshing with a bevel gear 26. The bevel gear 26 is secured to a sleeve 27 which is journaled in the base 21 and has rigidly secured to it a disc 29. Projecting upwardly from the disc 29 are pins 31 and 32. The pins 31 and 82 are adapted, when the motor is operated, to coil rod guided into the space between the pins by a tube 34. The pins 31 and 32 project through apertures 35 formed in a stripping plate 86 secured to a rod 38 which is slida'bly journaled in the sleeve 27 and is connected by a coupling 39 to a piston rod 40 secured to a piston 11 disposed in a pneumatic cylinder 42. The cylinder 42 is connect-ed to any suitable source (not shown) of fluid under pressure by means hereinafter described so that the fluid may be'admitted thereto to move the piston rod 40, the rod 38 and the stripping plate 36 upwardly in such inannerthat rod coiled uponthe pins 32 is stripped therefrom and raised to the level of a floor '18.

Posts 15 depending from a carriage 46 are adapted to push the coiled rod across the floor 43 onto a conveyor e8 driven by any suitable means (not shown) andadapted to deposit the coiled rod in a quenching hath (not shown) or the like. The carriage 46 comprises angle irons 50 and 51, the angle irons 51 being secured to the angle irons 50 and being arranged transversely thereof. The carriage 46 also comprises threaded blocks 53 which are secured to the angle irons 50 and engage horizontally disposed threaded rods 55. The threaded rods 55 are rotatably journaled in bearings 57 and 58 mounted upon a frame 60. Secured to each threaded rod 55 is a bevel gear 62 which meshes with a bevel gear 63 secured to a shaft section 64 journaled in a bearing 65 mounted upon the frame 60. The shaft sections 64 are operatively connected to each other by a shaft section 67 which is pivotally secured to the shaft sections 64 by pins 68. Secured to one of the threaded rods 55' is a sprocket 70 operatively connected by a sprocket chain 71 to a sprocket 72. which is secured to the shaft 73 of a three-phase motor 74, the motor 7 4 being mounted upon the frame 60. The motor 74 is connected by'suitable means hereinafter described to a 5 suitable source (not shown) of electricalenergy and maybe operated to rotate the threaded rods '55 first in one direction and then in the opposite direction to reciprocate the carriage 46.

The tube 34 is secured in a tubular casting 97 pivotally mounted upon a bracket 98 mounted upon vertically disposed brackets 99 which are in turn mounted upon the frame 60. The tubular member 97 is provided with a flaring mouth 100 which opens into the tube 34. Secured in the;

bracket 98 is one end of a tube 102, the other end of which is conveniently disposed with respect to a rolling mill (not shown); An aperture 104 in the bracket 98 opens into the tube 102 and is aligned with the month 100 when the tube 34 is in the position wherein it is shown in full lines in Fig. 6. The mouth 100 is spaced from the aperture 104 so that in the event rod is delivered by the tube 102 into the tube 34 when the coiling machine 20 is in a functionally inoperative condition, the rod maybe severed intermediate the tube 102 and the tube 34 and readily withdrawn therefrom. The tubular m mber 97 passes between rollers 106 jour naled upon pins107 secured in a slide 108 which is mounted in ways 109 formed on the brackets 99. The slide 108 is pinned to a piston rod 111 of a piston 112 disposed in a pneumatic cylinder 113. The cylinder 113 is connected to the'supply (not shown) of fluid under pressure by means hereinafter described which controls the admission of the fluid to the cylinder in such manner that the slide 108 may be reciprocated to bring thetube 34-intoand out of its functionally operative positionwith respecttothe coiling machine 20, thus permitting the tube 34 to be withdrawn from the path of the car- 145. The rod 145 is slidably journaled in bearings 146 and. is normally held by a compression spring 147 in a position wherein the contact 144 engages the contacts 142 and 143. A roller 148 is rotatably mounted in the lower end of the rod 145. The switch 140 is mounted upon the frame 60 in a position wherein a cam plate 162 mounted upon the carriage 46 will engage the roller 148 when the carriage is in its left hand position (Fig. 2) and will hold the roller 148 and the rod 145 in positions wherein the contact 144 will be spaced from the contacts 142 and 143. y

The switch 150 is substantially identical with the switch 140, the several parts thereof being indicated by the reference numerals 151 to 158, inclusive. The last digit of each reference character designating a part of the switch 150 is identical with the last digit of a reference character designating a like part of the switch 140. The switch 150 is mounted upon the frame 60 in a position wherein the roller 158 will be engaged by the cam 162 when the carriage 46 is in its right hand position (Fig. 2). The con tact 154 will then be spaced from the con tacts 152 and 153.

Theswitch 120 is mounted upon the base 21 in aposition-wherein arms 121 and 122 of bell crank lever 123 forming a part of the switch maybe engaged by a metallic roller 124 mounted upon and insulated from a bar 125'lixed to the coupling 39. The arm 122 has a slot 127 in which rides one end of a pin 128 projecting from a slide 130.

Mounted in the slide 130 and insulated from each other are contacts 132 and 133 which may be bridged bythe roller 124 when the roller is brought into a position wherein it is shown in Fig. 8 during the upward travel of the stripping plate'36. The arrangement is such that when the roller 124 moves upwardly it will engage a latch member 136 pivoted uponthe arm 121, will swing the latch member out of its path, and will then momentarily engage the contacts. 132 and 133 as it passes them. After passing the contacts 132 and 133 the roller 124 will engage thearm 122 and will rotate the bellcrank lever 123 in a counter-clockwise direction (Fig. 8) to m'ovethe pin 128, the

the left (Fig. 12), a distance which will. permit the roller 124: to return to its lowermost position without again engaging the contacts 132 and 133; During its down ward stroke theroller 12a engages the latch member 136 and rotates the bell crank lever 123 in a clockwise direction (Fig. 12) to restore the contacts 132 and 133 to the positions wherein they are shown in Fig. 12.

The relay 200 comprises a winding 211, an armature 212 having an extension 213, and contacts 215, 216, and 217 mounted upon and insulated from the extension. l y hen the winding 211 is energized,the contact 215 engages a pair of contacts 219 and 221, the contact 216' engages a contact 222, and the contact 217 engages a pair of contacts 223 and 224. Urged against the extension 213 by a compression spring 226 is a slidably mounted rod 227 carrying a contact 228 adapted to engage a pair of contacts 229 and 231 when the winding 211 is (lo-energized, the contact 228' being spaced from the contacts 229 and 231 when the winding is en ergized.

The relay 300 is substantially identical with the relay 200 and its parts are identified by reference numerals ranging from 211 to 231-. The last two digits of each reference character designating a part of the relay 300 are identical with the last two digits of each reference character designating a like part of the relay 200..

Referring to-Fig. 15, the main is connected to one terminal of the switch The main 116 is connected to' the contacts 133, 224, 222, e22, 331, and 321. A SBCOIlCl terminal of the motor 74% is connected to the contacts 223 and 323. The third terminal of the motor 74 is. connected to the contact 229. The contact 2'1'6is connected. to one terminal of the winding 211 and to the contact 329.- The contact 316 is connected t'oion'eterminal' of the winding 311 and to the contact 231.

The contact 142 is connected to the other terminal. of the winding 211:. The contacts 1&3 and 152 are connected'to each-other and to the other terminal of the switch 160. The contact 153 is connected to the other terminal of the winding 311. Fig. 15 diagram to. thesourcev (not shown) of fluid" under pressure and are connectedto the cylinder" 4.2.hy pipes 177 and 178. The valves? and 172 areconnectedto the cylinder 42 pipes and 181 and the valves 171 and 1.72 are connected to each other by a pipe 183. The cylinder 113 is connected to the valves 171 and 172 by pipes 185 and 186, respectively. Anexhaust pi-pe187 is connected to the valve 170. The valves 171 and 172 are provided with a common valve stem 190 to which is rigidly secured a bifurcated lever 191 adapted to be engaged by a pin 193 mounted upon the carriage 16. The construction is such that when the carriage travels to the right (Fig. 1) the pin 193 will engage the bifurcations of the lever 191 and manipulate the valve 171 and 172 so that the pipe 175 will communicate through the valve 171 with the pipe 183, and the pipe 183 will communicate through the valve 172 with the pipe 186. During; the return stroke of the carriage 16' the pin 193 will engage the bifurcations of the lever 1,91 and return the valves to the po= sition wherein they are shown in Fig. 16. Fig. 16 illustrates the condition which exists when rod is being coiled, the stripping plate being in its lowermost position and the tube 34 being in its functionally operative position with respect to the coiling ma chine 20.

In the operation of the apparatus the motor 22 is connected to any suitable source (not shown) of electrical energy by the operator and the rod is guided to the pins 31 and 32 through the tubes 102 and 3 1. When the rod has been coiled, the motor 22 is brought to a stop, and the operator manipulates the valve 17 Oso that fluid under pressure may flow through the pipe 17 1, the valve 170, the pipes 180 and 181, the valve 172 and the pipe 186 tothe cylinders 4:2 and 113, the fluid being delivered to the cylinder 42 by the pipe 181. The cylinder 113 then communicates with the exhaust pipe 187 through the pipe 185, the valve 171, the pipes 177 and 178, and the valve 170, and" the cylinder 12 communicates with the exhaust pipe through the pipes 181 and180, and the valve 170. The stripping plate36 is then forcedupwardly by the piston 11 to strip the coiledrod from the pins 32 and to raise it to'the level of the floor 43. Simul taneously therewith, the piston 112 is moved upwardly to swing the tube 3 1 out of the path of the carriage 16. During the stripping operation the roller 12 1- momentarily bridges the contacts 132 and 133, thus closing a circuit which may be traced as follows: From the contact 132 through the contacts 229, 228, 231, the winding 311, contacts-1-53, 154;, and 152', the switch 160, the main 115, the-main 117, the contact 133 and the roller 1224'. The winding 3 ll, then energized, causes the contact 316toengagethe contact 322, causes the" contact 315to engage the" contacts 319 and 321, causes the contact 317- to engage the" contacts 323and32, and causes: the contact' 328 to be Withdrawn from tor. The motor 74 when so operated rotates the threaded rods 55 in a proper direction to advance the carriage 46 toward the conveyor 48 so that the posts 45 will engage the coiled rod and push it across the floor 43 into the conveyor. During the forward stroke of the carriage 46, the pin 193 engages the bifurcations of the lever 191 and manipulates the valves 171 and 172 in the manner above described to connect the cylinder'113, directly to the pipe 175 so that the tube 34 will be prevented from returning into the path of the carriage 46 until the carriage has passed it during the return stroke. hen the coiled rod has been removed from the stripping plate 36, the oper ator manipulates the valve 170 in such manner that the pipe 174 is connected to the cylinder 42 through the valve and the pipe 178, the cylinder 42 being simultaneously connected with the exhaust pipe 187 through the pipes 180 and 181 and the valve. Preferably, the valve 17 0 is so manipulated directly after the posts 45 have removed the been advanced to the position wherein the posts 45 deposit the coiled rod upon the conveyor 48, the cam 162 engages the roller 158 and disengages the contact 154 fromthe contacts 152 and 153, thus de-energizing the winding 311 and causing the contact 328 to engage the contacts 329 and 331, causing the contact 328 to engage the contacts 329 and 331, causing disengagement of the contact 316 from the contact 322, disengagement of the contact 315 from the contacts 316 and 321, and dis engagement of the contact 317 from the con tacts 323 and 324. The winding 211 is then energized by current flowing in a circuit which may be traced as follows: From the main 115 through the switch 160 through the contacts 143, 144, and 142, winding 211, the contacts 329, 328, and 331, and the main 117. The motor 74 will then be connected to the mains 115, 116, and 117 in such manner that its directiono-f rotation will be reversed and the threaded rods 55 will be rotated toretract the carriage 46, the motor being connected to the source .of

. ing means.

electrical energy as follows: Through the main 115 to i one terminal of the motor; through the main 116, the contact 221, the contact 215, and'the contact 219 to a second terminal of the motor, and through the main 117, the contact 224, the contact 217, and the contact 223 to a third terminal of the motor. During the return stroke of the carriage 46, the pin 193 againengages the lever 191 and restores the valves 171 and 172 to the condition illustrated in Fig. 16 so that the tube 34 again assumes its operative position with respect to the coiling machine 20. When the carriage 46 enters its left hand position (Fig. 1) the cam 162 will engagethe roller 148 to disengage the contact 144-from th contacts 142 and 143. This de-energizes the winding 211, and the contacts of the relay 200 are restored to the positions wherein they are shown in Fig. 15, and the motor 74 is brought to a full stop.
